Results of a Phase 1 Study Assessing the Effect of CIN‐102, a Novel Formulation of the Dopamine Receptor Antagonist Domperidone Designed to Treat Gastroparesis, on Cardiac Repolarization in Healthy Volunteers
Why the study?
Does single-dose deuterated domperidone (CIN-102) prolong the QT interval compared to placebo in healthy volunteers?
Population
62 healthy volunteers
Comparison
Single doses of 30-mg and 100-mg deuterated… vs Placebo and moxifloxacin (positive control)
Design
RCT, 4-period randomized crossover
Key result
CIN-102 did not exert a clinically meaningful effect on QTc interval, with no ΔΔQTcF exceeding 10 ms at therapeutic and supratherapeutic doses.

Supports QT-safe CIN-102 use in practice; confirms deuteration mitigates domperidone’s QT effects.
Does single-dose deuterated domperidone (CIN-102) prolong the QT interval compared to placebo in healthy volunteers?
A novel deuterated formulation of domperidone (CIN-102) does not cause clinically meaningful QT prolongation at therapeutic or supratherapeutic doses in healthy volunteers.
Bond et al. (2026) studied this question. CIN-102 did not exert a clinically meaningful effect on QTc interval, with no ΔΔQTcF exceeding 10 ms at therapeutic and supratherapeutic doses.
